13 Claims.

This invention relates in general to dispensing containers and more particularly to a novel dispensing spout arrangement and closure therefor.

Among the objects of the invention, one object is to provide a dispensing container of this character wherein the spout and its closure are so constructed and organized as to provide for the drain-back or return into the container of any ID of the liquid which may not be entirely discharged or poured therefrom and also to provide not only for the closure of the discharge spout when the contents are not being dispensed but also 'for the complete and eflectlve protection of all areas of the spout over which liquid flows. These features especially adapt the container for dispensing beverages, syrups or the like, or, in fact, any substances which are liable to be contaminated'or impaired in any way upon exposure to air or to dust or foreign matter.

Another object of the invention is to provide a closure for a container of this character which may be conveniently so constituted as to be chemically inert with respect to the contents of the container.

A further object is to provide a device of the character described and having the advantages enumerated which is simple and durable in its construction, economical to produce, readily and easily applied and removed and yet when applied provides an effective and secure closure and also an hermetic seal.

Other objects and advantages reside in certain novel featuresof the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly I pointed out in the appended claims, reference be- -ing had to the accompanying drawings, forming a part of this specification, and in which:

' .40 Figure 1 is a perspective view showing a dispensing container embodying the present invention;

Figure 2 is a fragmentary view on an enlarged a scale showing one type of closure in diametrical vertical section, partshbeing shown in elevation for the sake of illustration; Figure 3 is a fragmentary view similar to Figure 2 but showing a slight variation in. the construction of the closure and spout;

Figure 4 is a fragmentary view partly in diametrical vertical section and partly in side elevaitio'n showing another embodiment of the invention'; and Figure 5 is a similar view showing a modifica- IB and compress and deform the same into setion of the form of the invention illustrated in Figure 4.

Referring to the drawings, and more particularly to Figures 1 and 2, the numeral I designates a container similar in its general construction to the container of my Patent No. 1,903,442, granted April 11, 1933. The head 2 of the container has an inclined portion 3 as in the patent referred to and in the inclined portion a discharge opening 4 is provided. A pouring spout 5 is as- 10 sociated with the discharge opening. Pouring spout 5 is generally of cylindrical form and has its lower end interseamed with the margin of the discharge opening as indicated at 6. The upper or outer end of the spout 5 is flanged as at I and is cut off or shaped to lie wholly within the confines of the container.

A closure is provided for the discharge openother suitable material. The section I0 of the 0 plug P has a reduced portion I I designed to project down through the discharge opening and also has an enlarged portion or shoulder I2 designed to fit against the seat I3 presented at the point where the spout is interseamed with the margin ofthe discharge opening. The shoulder I2 has a beveled outer peripheral portion or seat I4 and also has a recess I5 in its top, The upper part I! of the plug P has a reduced portion I8 slidably interfitted with the recess I5 and has a beveled peripheral portion I9 cooperable with the beveled portion It to define an approximately V-shaped recess in the periphery of the plug and intermediate the ends thereof. In the recess so defined, a sealing and securing element in the form of a ring or band of elastic material, such as rubber, is disposed. The beveled surfaces I 4 and I9 are designed to engage the rubber ring curing and sealing relation with the spout and with the plug. The parts III and H are drawn toward each other and into operative position by means of a wing nut 20 threaded on a screw 2| secured to the part III, and extending through an opening in the part II and in a cupped washer 22.

The form of the invention shown in Figure 3 is identical with that just described except that the spout and the head of the container are provided with annular grooves or recesses 25 to receive the securing and sealing element I6.

In the form of the invention shown in Figure 4 the container I has a head 2 and pouring spout 5 as before, and the construction of the closure is generally the same differing principally in the fact that it is made entirely of sheet metal and makes provision for sealing of the container.

Asillustrated, the inner section or part 30 of the plug is drawn from sheet metal into cup-like form and has around its upper edge portion a double flange formation 3i to provide a shoulder to engage against the seat I3 and to provide a beveled seat or surface 32 for the sealing element or ring it. The outer section or part 35 of the plug is also drawn from sheet metal into cup-like form and has a reduced portion 36 telescoping into the flange 32 and adjacent such reduced portion has a beveled surface 31 engageable with the gasket l6 whereby the sealing ring it will be compressed between said surfaces 32 and 31 and deformed into the annular recess 38 of the spout.

The follower is urged to operative position by means of a wing nut 39 threadedly engaged with a stud 30 which may have its head 4| welded to the plug 30.

This construction lends itself readily to the application of a sealing cap 42 which may be inter-crimped with the spout as at 43. This sealing cap may have the conventional tearing tab (not shown).

The form of the invention shown in Figure 5 is identical with that shown in Figure 4 with the exception that the inner part of the plug corresponding to the part 30 instead of being a sheet metal drawing or stamping is made of wood or other suitable material. In this figure the inner part is designated at 45 and as before has a shoulder 46 which engages against the seat 13 and provides a seat for the sealing element IS. A wing nut 39 is employed as before but the stud with which it coacts and designated at is designed for use with wood. The outer part or section of the plug is identical with that shown in Figure 4 and hereinabove described and is designated by like numerals.

A closure of the character described may be readily and easily applied and removed. When applied and secured in closed position the distortion of the sealing ring resulting from the action thereon of the cooperating beveled surfaces of the two parts of the closure plug provides not only for an hermetic seal but also for a secure mechanical interconnection. The embodiments of the invention shown in Figures 4 and 5 lend themselves also to the ready application of sealing devices required by law or by custom in connection with the distribution of some commodities.

While the invention in its various forms may be used to advantage with dispensing types of containers of the character shown, it is also adapted for advantageous use with other different and distinct types of containers. For example, it is capable of effective use with a pail type of container, that is to say, a container or receptacle which has an open upper end or an opening of substantial size in some other portion thereof. In any event, the invention makes use of the characteristics generic to the several modifications, namely, a sealing ring interposed between two cooperating parts which are drawn together to compress the ring and cause it to perform two functions, one the securing of the closure in place, and the other the sealing effect between the closure and the container.

While I have shown and described several constructions in which the invention may be advantageously embodied, it is to be understood that the constructions shown have been selected merely for the purpose of illustration or example and that various changes in the size. shape and arrangement of the parts may be made without departing from the spirit of the invention or .the scope of the subioined claims.
